Well, let's have a look. A submarine, ice-chair, robot, cannon, helicopter, water-bike, plane, bicycle, helicopter, unicycle, submarine, comb. Which of these exactly is an 'invention' (something that has not existed before)?
as for the vehicles... i guess if you have no family, no loved ones, and don't care whether you get crippled or drown or whatever, then these are great ideas.
